Description

Technical Field

[0001] The present invention relates to an automatic overflow device, and more particularly to an overflow device with adjustable height. Background Art

[0002] An automatic overflow device is a device for controlling the liquid level adopted by many devices or instruments. Once a traditional automatic overflow device is designed and installed, the overflow height cannot be adjusted. Authorization number: CN204065846 U discloses a self-overflow water tank with adjustable liquid level. Although this invention can adjust the overflow liquid level height, since the adjustment structure is installed on the water tank body, the liquid in the tank needs to be drained to adjust. If the liquid level is not lowered below the adjustment plate, the liquid in the tank will flow out during adjustment, causing pollution or loss.

[0003] To solve the above problems, the present invention discloses an overflow device with adjustable height. As long as this device is connected to the bottom of the liquid storage component of the device or instrument that needs to control the liquid level through a pipeline, the present invention forms a U-shaped tube structure with the liquid storage component of the connected device or instrument, and discharges the excess liquid by using the principle that the liquid levels at both ends of the U-shaped tube are horizontal. The installation is convenient and no major modification is required for the device or instrument. When it is necessary to adjust the liquid level height, only the switch of the set valve needs to be adjusted, and a small amount of liquid is discharged to adjust the liquid level height. The discharged liquid can be recycled without waste. Summary of the Invention

[0004] An overflow device with adjustable height includes an inlet and outlet pipeline, a locking component, a sealing component, and an overflow component. It is characterized in that: the inlet and outlet pipeline is provided with a pipeline, a valve, a connecting fitting, and a riser pipe; the overflow component is provided with an adjusting pipe, a liquid collecting pipe, and a drain pipe; the adjusting pipe of the overflow component is inserted into the riser pipe provided in the inlet and outlet pipeline and can move up and down; the overflow component cooperates with the riser pipe provided in the inlet and outlet pipeline through the locking component and the sealing component to achieve the purpose of locking and sealing. When it is necessary to adjust the height, close the inlet side valve, open the drain side valve. After the liquid in this device is discharged, loosen the locking component, adjust the height of the overflow component to the required position, then lock the locking component, close the drain side valve, and open the inlet side valve to work normally.

[0005] Optionally, the riser pipe is a hollow structure with external or internal threads provided at one end; a groove for cooperating with the sealing component is provided on the end face where the threads are provided.

[0010] Optionally, a scale is provided on the outside of the adjusting pipe to facilitate accurate height adjustment.

[0011] As long as this device is connected to the bottom of the equipment or instrument that needs to control the liquid level using pipelines, the present invention forms a U-shaped pipe structure with the liquid storage component of the connected equipment or instrument, and uses the principle that the liquid levels at both ends of the U-shaped pipe are horizontal to drain the excess liquid. The installation is convenient and does not require major modifications to the equipment or instrument. During operation, lock the locking component, close the drain side valve, and open the inlet side valve. When the height needs to be adjusted, close the inlet side valve, open the drain side valve, and after the liquid in this device is drained, loosen the locking component and adjust the height of the overflow component to the required position. The drained liquid can be recycled without waste. Description of the Drawings
